Yes and when I switch sources briefly it turns off my soundbar volume also when i turn volume back up with my humax remote which volumes my soundbar then the humax powers back on and switches sources again its very frustrating.
Update from android 9 to 14 - problem

That's because CEC is fundamentally flawed and can never possibly work correctly for all configurations. There is no proper specification for CEC and no interoperability testing between manufacturers, unlike for example USB or Bluetooth. Each manufacturer implements CEC differently, so it can never work properly. The only reliable thing to do is disable it everywhere, and where that doesn't work (as found on the Aura) use a CEC blocker eg from Lindy.
If I disable cec the sound stops working to the sound bar. The problem is it was fine before the update their should be a toggle to override it if it interferes with other sources, when I power off with my humax remote my TV humax box and soundbar powers off together anyway this new update as complicated things. When I switch sources briefly the faff of having to find the correct remote to turn the sound on or it switches sources back again. They have over complicated how cec was working one button to power everything off and on was good enough. A.cec blocker cec less adapter would stop it but then one button on my aura remote wouldn't power everything on thats how its always been.

Humax have changed the CEC behaviour. But given there is no proper spec or testing it is impossible to say whether it was correct before, is correct now, or neither. Or even that both are within "spec".
That's unfortunate obviously. But I always run with CEC fully disabled so if anything doesn't work like that I can return it for a full refund when it is brand new.

Subject: Heads-up: Humax Aura update can corrupt TV HDMI handshake & cause boot loops on other connected boxes
Hi all,
Posting this in case anyone else runs into a strange issue after a Humax Aura firmware update.
The Problem
Immediately after my Humax Aura completed an update, my secondary Android TV box (an Ugoos X4Q running Amlogic S905X4) started getting stuck in a continuous boot loop—cycling through its boot logo 4 or 5 times before finally managing to reach the home screen.
What Actually Caused It
At first, it looked like a failed update or power supply issue on the Ugoos box, and even unplugging the Humax Aura's HDMI cable didn't immediately stop the loops. However, it turned out that the Humax update had triggered an HDMI-CEC / EDID handshake conflict that left the TV's internal HDMI controller board stuck in a corrupted standby state. Even with the Humax disconnected, the TV was stalling the HDMI handshake while the Ugoos tried to initialize its display drivers during boot.

Even with the Humax disconnected, the TV was stalling the HDMI handshake while the Ugoos tried to initialize its display drivers during boot.
How to Fix It (If You Experience This)
- Unplug the TV from the mains for 30 seconds: Simply putting the TV into standby isn't enough. Pulling the mains plug completely drains the capacitors and clears the corrupted HDMI/EDID memory on the TV's switching board. Once powered back on, my Ugoos booted cleanly on the very first attempt.
- Disable HDMI-CEC on both boxes: Check Settings > Device Preferences > HDMI CEC on the Humax Aura (and on any other connected streaming boxes, as the update had actually toggled CEC back on inside my Ugoos).
- Separate the HDMI ports & lock resolution: Plug the Humax and secondary boxes into non-adjacent HDMI ports (e.g., HDMI 1 and HDMI 3) so they don't share an internal sub-switch, and disable "Auto switch to best resolution" on the secondary box if it supports a fixed output.
The persistent resolution box i had when set to auto resolution kept popping up. I have now set my frame rate to 50/60 then I have set my resolution to fixed 1080 50 and video upscaling changed from from auto to manual 5 in-between smoothest and sharpest. Display and sounds match frame rate from never to always.

That's particularly evil. It's a shame devices don't have a "No really, OFF even if another device sends an instruction to turn it on" option.
As do I, nothing else works predictably.

I don't really care what the default is - it's not having the option that is the insane bit and being forced to be subjected to the subsequent madness.
Exactly! freedom of choice to set up how you want your equipment to work. If I want it on I want it on.

There is more info coming about this CEC debacle tomorrow.
I think it will be something that I have to get used to, i can turn cec off on my TV and I can then switch sources no problem but I then have no sound from my soundbar which is no good and I doubt any more firmware updates will be issued as its not manufactured anymore.

That reads a bit over the top concerning cause and effect, and its analysis.
Which AI, and level, did you use to generate the bulk of the post?

I've done all that already only thing i haven't done is a full factory reset but will have to reinstall all my apps passwords etc.

You're right, i used AI to identity the faults but it was by rigorous testing and not invention. Even now the Aura is acting up. So, after more investigation I'll report back.

The laws the EU passes for car specifications are indeed a diktat. The manufacturers get together and decide what new "safety features" they want mandated, and then the EU mandates them. Even if it's stupid and unreliable lane keeping that cannot be turned off (to name but one).

If we're an EU member we have some avenues to do something about that. Outside there's absolutely nothing we can do.

How do you have everything connected? Are all your sources like the Aura connected to the TV and then the TV is the only thing connected to the sound bar? Or are all your sources connected to the soundbar and it then feeds the sound on the TV? (like how you would use an AVR). If you have alternative ways of connecting things up it might be worth trying them.
If you have your sound bar connected with HDMI if it is possible try to set it up with an optical lead instead, I had to do that in order to get audio from my TV to work on my AV amp.

Being in won't change a thing from that point of view.
